The SUPRO FUROR 22!

Here's a brief review:

The FUROR 22 features a single 6L6 power tube, two 12AX7 preamp tubes, and a rectifier tube (GZ34). This configuration provides a warm, articulate tone with a strong midrange presence. The amp has a natural, vintage vibe, with a smooth high-gain response and a nice bloom to the sound. sp furo 22
